[0002] During the production of valve cores, the surface of the valve core needs to be finely processed by grinding to make its surface meet the precision requirements of the process.

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] A valve core feeding mechanism one by one, as Figures 1 - 7 shown, includes a feeding component 1 and a conveying component 2. The feeding component 1 is used to feed the valve cores into the conveying component 2 one by one, and the conveying component 2 is used to feed the valve cores into the grinding machine equipment.

[0025] The feeding component 1 includes a first bracket 11, a hopper 12, a first feeding plate 13, a second feeding plate 14, a first driving member 15 and a second driving member 16. The hopper is used to hold the valve cores. The first feeding plate 13 is stacked on the second feeding plate 14, and the second feeding plate 14 is stacked on the inner wall of a side plate 121 of the hopper 12, and the inner wall of the side plate 121 is an inclined surface. The first driving member 15 and the second driving member 16 are respectively used to control the first feeding plate 13 and the second feeding plate 14 to reciprocate up and down along the side plate 121. A lifting part 131 is arranged at the upper end of the first feeding plate 13, and the valve core is lifted upward through the lifting part 131. A first guiding groove 141 allowing a single valve core to pass through is provided through the second feeding plate 14. The first feeding plate 13 is used to feed the valve cores into the first guiding groove 141, and the second driving member 16 is used to drive the second feeding plate 14 to move upward, so as to drive the valve cores to move to a position higher than the side plate 121 of the hopper 12, so that the valve cores fall into the conveying component 2 one by one.

[0026] In an embodiment, as Figures 1 - 7As shown, the lifting part 131 is an inclined surface that slopes towards the second feeding plate 14. A V-shaped groove is formed between the lifting part 131 and the second feeding plate 14 to lift the valve core. To achieve the sequential feeding of the valve cores, only one valve core can be axially stored on the lifting part 131. However, during the feeding process, it is inevitable that there will be a situation of material accumulation, that is, two or more valve cores are stacked on the lifting part 131. Therefore, the size of the first guiding groove 141 is set to allow only a single valve core to pass through. When the first feeding plate 13 pushes the valve core to move upward along the second feeding plate 14 and reaches the first guiding groove 141, one valve core falls into the first guiding groove 141, and other valve cores cannot fall into the first guiding groove 141 and will move downward together with the first feeding plate 13. The second driving member 16 drives the second feeding plate 14 to move. Since one end of the first guiding groove 141 is blocked by the side plate 121 of the hopper 12 when the second feeding plate 14 is in the initial position, the valve core will be temporarily stored in the first guiding groove 141. When the second feeding plate 14 moves upward to open the first guiding groove 141, the valve core will slide out along the first guiding groove 141 into the conveying assembly 2. In addition, a guiding plate can be installed on the side plate 121 of the hopper 12 to guide the valve core sliding out from the first guiding groove 141 into the conveying assembly 2.

[0027] In the above embodiment, as Figures 1 - 7 shown, the first driving member 15 and the second driving member 16 are air cylinders.

[0028] In one embodiment, as Figures 1 - 7 shown, a guiding hole is provided at the bottom of the hopper 12. The stirring rod 17 is slidably arranged in the guiding hole. The stirring rod 17 is connected to the first driving member 15, and the first driving member 15 is used to drive the stirring rod 17 to move up and down synchronously with the first feeding plate 13. The stirring rod 17 cooperates with the guiding hole to assist in guiding the up and down movement of the first feeding plate 13. At the same time, the stirring rod 17 extends into the hopper 12 and can stir the valve cores in the hopper 12 to prevent the valve cores from getting stuck between each other, causing the first feeding plate 13 to be unable to reliably convey the valve cores.

[0029] In the above embodiment, as Figures 1 - 7 shown, the number of the stirring rods 17 is not limited to one, and two or more can also be set. Preferably, the number of the stirring rods 17 is set to two. The two stirring rods 17 are arranged at intervals.

[0030] In one embodiment, as Figures 1 - 7 shown, a discharging part 132 is provided on the side of the lifting part 131. The discharging part 132 is an inclined surface that slopes towards the inner cavity of the hopper. The discharging part 132 is used to prevent the valve core located at the discharging part 132 from moving upward with the first feeding plate 13. Through the cooperation of the discharging part 132 and the lifting part 131, the first feeding plate 13 can only axially carry one valve core at a time.

[0031] In one embodiment, as Figures 1 - 7 shown, the thickness of the first material guiding groove 141 can only stack one valve core. The thickness of the first material guiding groove 141 is determined by the thickness of the second feeding plate 14; when the second feeding plate 14 is in the initial position, the lower end of the first material guiding groove 141 is blocked by the side plate of the hopper 12, and the first material guiding groove 141 forms a storage groove with an opening in one direction. Only one valve core can be stacked and accommodated in this storage groove, thereby realizing the feeding of valve cores one by one.

[0032] In one embodiment, as Figures 1 - 7 shown, the conveying assembly 2 includes a belt conveyor 21 and a material guiding plate 22. The material guiding plate 22 is installed on the belt conveyor 21, and a second material guiding groove 221 that converges towards the middle is formed on the material guiding plate 22; the second material guiding groove 221 is used to guide the valve core to fall onto the belt conveyor 21 and move along the length direction of the second material guiding groove 221. Specifically, the second material guiding groove 221 consists of two parts, including a first guiding part 2211 and a second guiding part 2212. The first guiding part 2211 includes two inclined surfaces that converge from top to bottom and from outside to inside, and the valve core is guided by the first guiding part 2211 to move towards the second guiding part 2212; the second guiding part 2212 includes two parallel vertical planes, forming a guiding groove for guiding the axial movement of the valve core. When the valve core is being conveyed, the valve core that falls from the feeding assembly 1 into the conveying assembly 2 is first guided by the first guiding part 2211 into the second guiding part 2212. The valve core lands on the belt conveyor 21, and with the operation of the belt, the valve core is driven to move towards the discharging end. According to the time for the feeding assembly 1 to convey one valve core, the conveying speed of the belt conveyor 21 is adjusted, which can ensure that the valve cores are fed into the grinding machine one by one.

[0033] The above are only the preferred embodiments of the present utility model and are not used to limit the scope of implementation of the present utility model; if the present utility model is modified or equivalently replaced without departing from the spirit and scope of the present utility model, it shall be covered by the protection scope of the claims of the present utility model.
